Daily rhythms in behavior, physiology and metabolism are controlled by endogenous circadian clocks. At the heart of these clocks is a circadian oscillator that keeps circadian time, is entrained by environmental cues such as light and activates rhythmic outputs at the appropriate time of day. Genetic and molecular analyses in Drosophila have revealed important insights into the molecules and me...

background: cardiovascular diseases refer to a group of diseases that affect the cardiovascular system principally cardiac diseases, vascular diseases of the brain and kidney and peripheral arterial diseases which are caused by various factors. considering the importance of nutrition education, especially the intake of fruits and vegetables, this study was performed to determine the effect of h...

In this article the structure of subjective well-being (SWB), the relationship between household income and SWB and mean differences in components of SWB in China and the USA are investigated. Both China and the USA were characterized in a three-factor model of SWB (life satisfaction, positive affect and negative affect). Household income was more strongly positively correlated with the three m...

Low-temperature series have been derived for the q-state Potts model on the Kagomé lattice (q = 3 and 4) and for the 3-state honeycomb lattice. The series are derived by the finitelattice method, with many additional terms obtained by noting the structure of the correction terms. Accurate estimates of the critical points are found, which confirm exact, but not rigorous results in the case of th...

We construct the quantum oscillator interacting with a constant magnetic field on complex projective spaces I CP, as well as on their non-compact counterparts, i. e. the N−dimensional Lobachewski spaces LN . We find the spectrum of this system and the complete basis of wavefunctions. Surprisingly, the inclusion of a magnetic field does not yield any qualitative change in the energy spectrum. Fo...

In this paper a new form of the homptopy perturbation method is used for solving oscillator differential equation, which yields the Maclaurin series of the exact solution. Nonlinear vibration problems and differential equation oscillations have crucial importance in all areas of science and engineering. These equations equip a significant mathematical model for dynamical systems. The accuracy o...

This paper proposes a novel methodology for AMS SoC formal verification based on Hybrid Scheme combined with symbolic computing and LHPN model, FV-HS. The paper is concerned with a class of AMS designs, continuous-time AMS designs i.e., tunnel diode oscillator for research target. Firstly, Labeled Hybrid Petri Net model is established for safety property verification of tunnel diode oscillator,...
